Move over, CPUs. The GPUs have arrived in modern enterprises,
and data scientists are eager to use them for their modeling and deep
is this happening, and what are the advantages GPUs bring for Data Science applications?
Read on and find out.
What Are GPUs?
or graphics processing units, have been used for decades in the gaming industry
and became more popular when Sony first used the term with reference to its
PlayStation console. They have been essential for the fast rendering and
processing of computer games, revolutionizing the experience for gamers as
graphics became more and more detailed, nuanced, and realistic.
GPUs were designed to render graphics through rapid mathematical calculations,
it is this high-performance processing that makes them appealing for Data Science.
It enables AI to learn from images and sounds, using massive amounts of image
and sound inputs for these deep learning processes.
make this a reality, GPUs power neural networks being trained at scale so that
end-users can enjoy image, video, and voice-based applications as well as the
recommendation engines so many of us use, whether it is to find a good
restaurant or our new favorite sneakers.
How Do GPUs Make an Impact in Data
of us are familiar with the need for good processing power to get our work
done. That applies to our laptops and desktop computers as well as larger
infrastructure such as servers, switches, and, of course, the network we all
term CPU, central processing unit, is commonplace and describes the main
processor within a computer, the “brain” of the machine that executes
instructions and programs.
In Data Science, Python libraries have become increasingly efficient at utilizing the existing CPU power available. When you want to work with hundreds of millions or even billions of records, running deep learning applications, however, CPUs will not be sufficient.
GPUs with their powerful parallel processing architecture, which allows
organizations to run, for example, forecasting models across millions of
possible product combinations for their retail stores to inform, plan, and
optimize their warehousing operations.
GPUs and the power they bring to Data Science opens up new opportunities for data scientists, analytics departments, and the organization as a whole.
process sequentially, while GPUs process in parallel. So even a large cluster
of CPUs cannot achieve the same performance as the right architecture of GPUs
for training deep learning algorithms.
imagine this optimized parallel architecture of GPUs combined with the
massively parallel processing built into your database. Your database software
and hardware are now perfectly aligned for the AI tasks you want to complete,
both benefiting from each other and utilizing each other optimally.
test the performance of our database running on GPUs, we trained a model in
TensorFlow, using a dataset of fine food reviews from Amazon. The dataset
contains 500,000-plus reviews from over 10 years. Our model is designed to
predict the score for each product, based on the text of the review, where we
want to analyze the sentiment. We can then compare the predicted score with the
actual score that is available in the data but not being used in training.
dataset contains categorical, numerical, and text data, making it a nice
challenge for our model, which is based on a pre-trained model in TensorFlow,
called Universal Sentence Encoder. The complexity of the dataset creates an
interesting use case for GPUs, because not only do the different data types
require specific encoding strategies, but the large amount of text also
requires a large model, which will be a good test for our GPUs.

our tests, we used the following setup on Google Cloud Platform (Region: Iowa):
- 1x NVIDIA Tesla K80
- 1x NVIDIA Tesla V100
- 1x CPU with 8 cores
- 1x CPU with 32 cores
comparing the performance of GPUs and CPUs for training our model, the K80
completed each epoch 9.9 times faster (72sec versus 710sec) than the CPU with 8
cores and 2.9 times faster (72sec versus 210sec) than the CPU with 32 cores.
V100, the most advanced GPU currently available in the cloud, completed each
epoch 28.4 times faster (25sec versus 710sec) than the 8 core CPU and 8.4 times
faster (25sec versus 210sec) than the 32 core CPU.

developing, training, and refining their models. They provide a more cost-effective
option for loading and manipulating data at this scale than CPUs and therefore

Given the demand for data scientists in the market and the value organizations should place on their skills, GPUs provide great opportunities for enabling data scientists to spend more time focusing on value-added tasks and experience fewer frustrations stemming from slow-performing systems and tools.

or in a hybrid model.
